| 中文摘要: |
| 利用逆复合二次径向基函数无网格配点法对Reddy的高阶剪切变形理论进行离散,预测了对称复合材料层合板的自由振动特性。将不同材料参数、几何尺寸和边界条件的层合板固有频率计算结果与相关文献中的结果进行对比,结果表明:逆复合二次径向基函数在对称复合材料层合板自由振动分析方面具有收敛性好及精度高等一系列优点。 |
| 英文摘要: |
| Higher-order shear deformation theories of Reddy discretized by a meshless collocation method based on the inverse multiquadric radial basis function are used to predict the free vibration behavior of symmetric laminated composite plates. Natural frequencies are computed for various material parameters, geometry parameters, boundary conditions of laminated plates, and compared with some available published results. Through numerical experiments, the high numerical accuracy and good convergence of the inverse multiquadric radial basis function method for free vibration analysis of symmetric laminated composite plates are demonstrated. |
